Which is a typical symptom of posttraumatic stress disorder?

Flashbacks are a hallmark symptom of posttraumatic stress disorder (PTSD). Individuals with PTSD often experience intrusive memories that can make them feel as though they are reliving the traumatic event. These flashbacks can be triggered by various stimuli reminiscent of the trauma, such as sights, sounds, or smells. They are vivid and distressing, contributing significantly to the emotional turmoil associated with the disorder.

In contrast, excessive worrying is more characteristic of anxiety disorders, insomnia can be a symptom across various mental health conditions, and anxiety attacks, though related, do not specifically define PTSD. Therefore, the presence of flashbacks distinctly identifies PTSD and highlights the impact of trauma on memory and emotional processing.
